hehe i think jeane is cute
and the entire fanatic attitude add soo much more to the plot
anyways, in the ANIME ( i know it goes VERY off) Marco and jeane come to somewhat like yoh, in their own unique way

Jeanne...is certanly unique...I didn't like her when I first saw her.Guess who she is too much like? Dum Dum Dum...XP
But I kinda got used to her way of being. Too pure for my taste, but 10+ for the complexity of this character.

I find the characters of X-Laws kinda not well developed in the manga. There's hardly any info about the characters and only a few like Marco and Jeanne has some background info in it.

It would be nice if the characters of X-Laws are powerful shaman and less impulsive. The characters probably took some time to be created but it was so easily killed in the manga series and perhaps anime as well. I wish they would be somewhat powerful like Hao's minion or the Gandara team...

Jeanne hardly appear much and only fought twice in the manga series while others were saving people, talking and such. Marco has fought quite a few while the others despite looking good they don't show any awesome fight but instead get pwned easily even in groups -_-;

Overall I like the concept of X-Laws; Iron maiden Jeanne, mecha angel-like spirits, outfit and such but sadly the characters are not well developed.
